Custom Thick Film Heaters
Ohmite's thick film resistors can be effectively used as heaters due to their ability to convert electrical energy into heat energy. When an electric current flows through the thick film resistor, electrical resistance causes the current to dissipate energy in the form of heat. The substrate on which the thick film resistor is printed provides thermal stability and helps to evenly distribute heat. It can withstand high temperatures and aids in efficient heat transfer.
The thickness and composition of the resistive layer determine the resistance value and the heating capacity. A thicker layer or one with higher resistivity will produce more heat for a given current. The resistive material is often patterned to control the current path, allowing for uniform heating. The geometry of the pattern can be adjusted to achieve the desired heating profile.
Applications
- Heated Surfaces: Thick film resistors can be used to create heated surfaces by embedding them into or attaching them to various substrates. These are commonly found in applications like heated seats, warming plates, and de-icing systems.
- Precision Heaters: Due to their precise control over temperature and uniform heating capabilities, thick film resistors are used in scientific instruments and laboratory equipment where specific temperature profiles are crucial.
- Industrial Heating: Thick film heater elements are used in industrial applications for heating gases, liquids, or solids. They are particularly useful in situations where compact, reliable heating elements are needed.
Advantages
- Uniform Heating: The design flexibility allows for even distribution of heat across the surface.
- Compact and Lightweight: Thick film heaters are thin and can be integrated into various forms without adding significant bulk.
- Rapid Response: They have fast thermal response times due to the direct conversion of electrical energy to heat at the resistive layer.
- Durability: The ceramic substrate and robust materials used in thick film technology provide longevity and reliability even under harsh conditions.
